Using whatever plastic sheeting that can be found, Afew larger, sturdy buildings have all windows and openings covered in plastic sheeting, which is fastened down with Duct tape. Survivors are encouraged to evacuate to these buildings or prepare their own residence with plastic and tape around windows. food and pre-bottled water supplies are ordered to be spread to the evacuation buildings, and prepared to be rationed if necessary. Military personnel are stationed to guard these resources incase panic occurs.
anything useful is picked up and placed indoors.
(OOC: wouldn't after about 200 years the Radstorms be over? I remember on Nexus something about this topic, to which it was mocked as "Fellout" instead of Fallout... I can't find the topic as of now..)
